ABSTRACT:
In a diazo copier, a first developing chamber for developing a diazo material employing an ammonia-containing vaporous developer, a second chamber adjacent an output aperture of the first developing chamber, a source of heat, and a suction device for drawing off developer escaping from the second developing chamber through an output aperture and for removing developer from the diazo material are provided. A rotatably mounted porous hollow roller means forms part of said suction device positioned in said second chamber and a suction duct means is connected to said roller means. A transport means which is not in heat-conducting connection with the source of heat is provided for bringing the copying material in contact with the hollow suction roller means.
